FORK FOR WEIGHING HAY.

SPECIFICATION forming part of Letters Patent No. 268,747, dated December 5, 1882,

Application tiled 'March 25. 1882. (No model.)

To all whom it may concern.

Be it known that I, GEORGE A. STEWART, a citizen ofthe United States, anda resident of Wells Tannery, in the county of Fulton and State ofPennsylvania, haveinvented a new and valuable Improvement in Weighing Hay- Forks, and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation ofthe saine, reference being had to the annexed drawings, making a part ot' this specification, and to the letters and figures ot reference marked thereon.

Figure 1 of thedrawings is a representation ot' a vertical sectional view of my improved fork, and Fig. 2 is a side view of the same.

Thisinvention has relation to weighing-forks f'or hay and straw; and it consists in the construction and novel arrangement of the knobsection of the handle, its screw-rod and regulator, connected to the movable index, the spring, the fer-rule, and the transverse pin holdingtheknob-sectiou ofthe handlein locked position when the Weighing devices are not in use, all as hereinafter set forth, and particularly pointed out in the claims appended.

In the accompanying drawings, the letter A designates the main part or body of the handle, which is attached to the fork B. The end of this part A ofthe handle is bored centrally, as indicated at c, the bore being larger at its outer part and serving to form a seat, d, for the operating-spring c, the ends of which bear against a shoulder, g, in the bore and against the end ofthe knob-section H.

K represents a slotted register-plate, which is duly graduated with a weight-scale, as indicated at- I. Under this plate is a slideway, m, in which is located thc movable index-slide s, which is provided with a lug, fu, having a threaded aperture, a, said lug being designed to extend through a slot, b, into the bore c of the handle.

L represents a ferrule, whichsurrounds the end ot' the main section A ot' the handle, and extends beyond the end thereof to receive the stemt of the knob-section H. To the knob-section is firmly secured the end ot' a rod, l1, which, passing through the spring e, extends into the bore c of the handle. The end k of this rod lz is threaded to engage the threaded hole in the lug v ofthe index-slide s.

In operating the weighing devices the fork is thrust into the hay, and then raised perpendicularly and rested on the knob-section. In this position the weight on the fork will depress the main handle-section Auntil the spring c, which supports it t'roxn the knob-section, is equalized, the index-slide then pointing out the weight on the scale. Should the spring be weakened or inaccurate in its relation to the index and its bearing on the shoulder ot' the knob-section, the relative position ofthe index can he properly adjusted by turning the connecting-rod lt in the lug n.

When thepweighing devices are not in use the knob-section is designed to be secured to the coupling ferrule by means of a. transverse pimp, having notches u, audextending through perforations z in the ferrule and knob-section.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a weighing-fork for hay and straw, the

knob-section H, having a rigidly-secured screwrod, h, extending into the bore ot' the handle and engaging the threaded aperture ct ot' the lug o ot' the index-slide, substantially as specitied.

2. A weighing-fork for hay and straw, having the bore o, internal shoulder, g, slideway m, and scale-plate K, the spring c, index-slide s, and its lug e, having the threaded aperture a, the coupling-ferrule L, knob-section H, and threaded connecting-rod and regulator h, engaging the lug t, substantially as specied.

In testimony that I claini the above I have hereunto subscribed my naine in the presence of two witnesses.

GEO. A. STEWART.
